Bound By Flame

This is for completing all of Randval's quests.

Act 1 - The Duel - beat him in a duel.
The Recruitment of Randval - talk to Captain to get him to join the Blades.

Act 2 - Randval the Loner - talk to him at the camp and agree to let him do a recon.
- once he returns agree to go attack the convoy with him. (Save before hand because if you take the wrong path you will fail - listen to him if he says "that's not the right way")

Water of life or death - this is part of the main questline if you sided against the Prince at the end of Act 1. If you sided with the Prince, this quest doesn't appear but the achievement will still unlock after completing the others.

Act 3 - A Knight in Distress - You will get separated from your party, after you get the quest to obtain the crystals, be on the look out for a 2 (secondary mission) on your map to find Randval fighting some monsters - help him slaying the monsters.

Once the battle is over and Randval engages you in conversation the achievement should pop.
